DO NOT change the stock on the shockwave you will make it a (illegal) NFA firearm and need a $200 tax stamp and a ton of paperwork here is a good article on the shockwave http://girlsjustwannahaveguns.com/gun-review-mossbergs-590-shockwave-shotgun-completely-legal-totally-badss/

again it is not legal to change the overall length or put a sholder stock on the shockwave. The stock referenced (Steve P) below would not fit as it is for a 20 gauge Mossberg 500 receiver and the shockwave is on a 12 ga (larger) receiver "ATI Talon T2 6 Position Adjustable Stock/Forend Package, Black for Mossberg ******20 Gauge"

*****STOP***** If you make modifications to the gun, including the addition of a shoulder stock or reduction of its overall length to less than 26″, you’re back in NFA territory which is the same as a "Silencer". Once you own a Shockwave, don’t monkey with it unless you complete the required NFA paperwork first.
